A strong final recommendation is usually short, top-down, and decision-oriented. Start with the answer, support it with the two or three most important reasons, and then mention key risks or next steps if relevant.
Many candidates ramble because they feel pressure to show everything they did. But the recommendation is not a replay of the case. It is the executive summary of your conclusion.
If you train yourself to lead with the answer and then support it cleanly, the ending becomes much stronger. You may also find it helpful to read finishing a case recommendation strong if you want a more structured way to practice this.
